What Collmex does

Collmex GmbH is a Saarbrücken-based software company founded in 2003 by former SAP AG developers, operating a cloud-only accounting and ERP platform targeted at small businesses, freelancers, and associations in Germany. Its product portfolio spans four lines: Collmex Komplettpakete (basic, plus, pro) at €16.95–€46.95/month combining accounting, invoicing, inventory, and e-commerce order import; standalone Buchhaltung tiers (free, light, basic) at €0–€11.95/month; standalone Rechnung tiers at €0–€11.95/month; and Collmex Verein at €13.95/month for clubs and associations. The platform is built around German regulatory requirements, including DATEV SKR03/SKR04 chart of accounts, Elster VAT submission, GoBD-compliant tax audit export, and EN 16931 electronic invoicing, with an HTTP POST/CSV API and integrations into Shopware, Magento, WooCommerce, Shopify, modified e-commerce, eBay, Sage payroll, FinTS/HBCI online banking, kontool BI, PayJoe, and Pixelletter postal/fax delivery.

The company runs a pure product-led growth model: customers self-serve through collmex.de, start a 30-day free trial, and convert to monthly direct-debit subscriptions with email-only support and no sales team. Add-on revenue comes from storage expansion (€11.95/month per 100k documents) and additional users (€11.95/month). Infrastructure runs on PlusServer's TÜV SÜD-certified data center in Köln (ISO/IEC 27001:2022, ISO 9001:2015), reinforcing a 'Cloud-Software made in Germany' positioning. Collmex reports over 10,000 customers won cumulatively and states it has been profitable for many years; it is privately held by management, led by Geschäftsführer Bastian Wetzel, with no external investors or parent company. Revenue is not publicly disclosed.

Scale indicators4 records

Recent moves6 records

Expansion highlights5 records

Regional players

• Bexio: Swiss SMB cloud accounting and ERP platform with very similar subscription tiers, DATEV-style localization and target customer profile. Comparable business model and product scope but serves Switzerland rather than Germany.

Emerging players

• Candis: Berlin-based AI-driven bookkeeping automation platform for German SMBs and accountants. Overlaps with Collmex's automation thesis but focuses on AI-based document capture rather than broad ERP.

Direct peers

• FastBill: German cloud invoicing and accounting platform for SMBs and freelancers with e-invoice support and bank integrations. Overlaps directly with Collmex Rechnung and Collmex Komplettpaket offerings in the German SMB market.
• Lexoffice: Haufe Group's cloud accounting SaaS for German SMBs and self-employed professionals. Competes head-to-head with Collmex on online bookkeeping, DATEV compatibility and tiered subscriptions, with a larger parent company behind it.
• BuchhaltungsButler: German SMB cloud accounting software offering bookkeeping, invoicing and bank reconciliation in a self-serve SaaS model. Directly comparable to Collmex on customer segment (small businesses, freelancers) and product positioning.
• sevDesk: German cloud-based accounting SaaS targeting freelancers, self-employed and small businesses with subscription tiers and bank integrations. Closest direct competitor to Collmex in product scope, target customer and pricing model within the German SMB segment.
• WISO MeinBüro (Buhl Data Service): Established German SMB business software suite covering accounting, invoicing and order management. Targets the same small business and self-employed segments as Collmex with comparable self-serve pricing.
• Debitoor (Sage): Cloud invoicing tool for freelancers and small businesses, now part of Sage. Directly comparable to Collmex Rechnung line in feature set and customer persona.

Broad incumbents

• DATEV: Dominant German cooperative provider of accounting and tax-advisor software. While primarily serving Steuerberater, DATEV shapes SMB software standards and is the reference ecosystem Collmex integrates with; an indirect incumbent to compete against for end-customer mindshare.
• Sage Business Cloud Accounting (Germany): Global accounting SaaS vendor with a localized German edition aimed at SMBs. Wider portfolio (payroll, ERP) competes with Collmex's Komplettpaket but with significantly larger scale and brand.
